If the intercompany Purchase Order triggers the approval process, this error message is triggered. However, this doesn't stop the transaction, since the Purchase Order goes to approval process anyway. Once approved, the Order can be processed without issues. 

This scenario is not applicable for Orders that do not meet the conditions from approval process.
